Unirse STATES WILLIAM E. WARD, OF LONG VBELAJIIH,lCALIIFvlR-ITJIA.

Application filed October 6, 1926. `Serial No. 139,825.

An object oi' my invention is to provide a. sash fastener which will eiiectively secure the windows against iurther opening in any desired position.

Another object iste provide a sash fastener which may be readily released or engaged as desired., and with a minmum of eitort.

A still further object is to provide a sash Yfastener which is simple in construction, in expensive to manufacture and highly eliective in operation. Y

Other objects7 advantages and features of invention may appear from the accompany ing drawing, `snbjoined detailed description and the appended claims.

ln. the drawing- F 1 is a fragmentary, longitudinal, s ectional view ot a pair oli window sashes with my 'fastener in position7 thereon.

Fig. is a side eievatioi'i of my fastener.

Fig. 3 is a plan view of the same. V

Referring more particularly to the drawing:

The numeral l indicates'the upper window sash and 2 the lower sash. A plate 3 is secured to the top oi the sash 2 adjacent the side thereof, the said plate being secu ed to the sash by a plurality of screws Il. or the like. A wedge member 5 is mounted on the plate 3 and comprises an inclined wedge 'face (i, said 'face being` adjacent the upper sash ,l and is inclined away Yfrom said sash.

The member 5 may be Yiba-med either a casting` integral with the plate 3, orv a 'single strip ot metal muy be bent to i'orm the inclined wedge 6 and may then be bent downwardly as at 7, and may be suitablyv secured to the plate 3 by rivets 8, or similar fas toning'.

A roller 9 is jonrnaled between a links l0, l() and a pin l1 extends'through the linls l() at the end opposite the roller 9.

The pin l1 being positioned inside of the pair of.`

wedge member 5 so that the roller 9 is mov-` ably mounted thereon. In operation the windows are moved to any desired'position nther open or closed and the roller 9 is then moved to the position'shown in Fig'. l; that is, it is wedged between the sash l and the inclined wedge G. Thus it will be seen that an Vatten'ipted upward movement ot the'sash 2 or a downward movement of the sash l; will only serve to wedge the roller 9 more firmly between the sash l and inclined wedge (j thus securelyholdingthesashes 1,2v against relative movement.` The wedging of the roller 9 between the windowandthe member serves to torce the sashes l, 2 aiart, and thus further aids in preventing` relative'movement of the windowby binding` the sashes against their guides.

To prevent accidental displacement ot the roller 9 when it is in fastening position, a stop lug` l2 is provided on the inside ot the wedge member 6 against which the pin 11 rests; thus preventing` an upward movement ot the roller 93 links'lO and pin 1l. XVhen it is desired to release the windows the roller 9 is lifted upwardly and swung' to the position shown in Figures 2 and 8, at which time the windows are free to move.

Hai/'ing' described my invention, I claim:

In a window con'lprising' upper and lower e lsashes, a plate secured to the top ot the lower sash, a wedge member secured to Vslid plate.
